You might try setting the air flow to the face position only rather than the blend setting. It really shouldn't make any difference but automotive A/C systems will open the outside air when they're in defrost or a blend setting that includes defrost. They do it for humidity control and to avoid window fogging. My GM pickup truck has a known issue with the recirc door operation and the fix is a reprogram of the HVAC control module.

I can't tell from your video whether the A/C issue you're describing is a recirc door problem or a total A/C shutdown where the compressor clutch deactivates. If it's just the recirc door you should still have functional A/C but slightly less cooling.

mine is always been on face only ...and this morning i jumped in started the jeep up turned it on high and REC face position and walla one block from the house complete shut down ...blower and cold air just shuts off for about 4 seconds and then back on ... and i do meen it shuts completly OFF ? ya Dale it is not just the door you can really tell DEAD silenice and no air ..and to me it seems it comes back kind of violently like a small surge when it reingages

a recall would be for a a issue that comes up ALOT. how many threads have i seen on a 012 a/c. ah ya this one. sounds like somethng is out of sorts. my wifs car need a new compressor. my mechanic that i have known a long time trust did the work 3 days later the a/c goes out again. no biggy take it back he gets another new part, the pully snaps off when he starts it. calls me, so we order a factory replacment now at 2x the cost. for the part. part comes in its from the same da^n company? same freaking box same part? but it has worked now for years. like Gump said" you never know what you get in a box of....

Definitely a/c only? I have heard of a blower motor that will shut down while the compressor clutch disengages to keep cold air in the car, or out of the car in the winter. The only other thing I can think of is your evaporator is icing up because you're low on refrig. If the fan can't push air through the coil it will fall off the fan curve and cavitate. I've seen auto blowers (and a lot of others) shut themselves down on internal motor overload, because they're not getting the cooling they need from airflow. then it slams back on when the motor thermistor switch closes. Maybe Jeep has an automatic recirc/fresh air setting that automatically shifts damper position to try and get more air over the coil? Or it requires dict static pressure to keep the damper position once it switches? That last part is just a theory but the engineering bits are true.

Me too. 2012 JKUR. Manual air, manual tranny. Just over 2k miles. The other day heading out of my neighborhood, air blowing on a setting of medium- high and on fresh. When all of a sudden the fan blower stops and around 3 seconds later it starts again. Have not had it happen again. Yet.

Same here. I have a 2012 JKUR with manual HVAC controls. Sometimes the A/C will cut out completely for a few seconds and come back on again. For me, it seems to happen after going over a bump, but not after every bump, just once in a great while.

I've also noticed that when I turn the engine on, if the HVAC blower has been left on from earlier, the blower takes a few seconds to turn on. I figured this was normal, allowing the engine and critical systems to get running before starting accessory systems. I've also noticed that the HVAC blower will cut out momentarily if I nearly stall the engine (I a manual transmission).

This is an AC system control unit issue. We have experienced the same thing, with AC cutting in and out, on our 2012 Sport. We have only 4K miles on the Jeep. The dealer is replacing the AC control unit. Even for those of you that have taken yours to a dealer I suggest taking it back or to another dealer becasue they obvioulsy now know about this issue.

I think to all of you experienceing this, that video says a thousand words... You know full well that the Jeep won't do it with the Tech in it.... If you can get some evidence to clearly show what it's doing, it might save you several trips back home to mommy...
